A planned rally on the border "could be replaced by celebrations at the Khiam detention center," four kilometers from the border, the source told The Daily Star.

The IDF is taking extra precautions and preparing a firm but non-lethal
response to any attempt to force the nation’s borders in the coming
days, as Palestinians plan mass marches to mark Arab losses in the Six
Day War.

Near Moshav Avivim, troops have fortified the border fence with Lebanon
and set up new lookout posts, the radio station reported.

The IDF Northern Command has ordered soldiers on the Syrian and Lebanese
borders to follow the usual rules of engagement before opening fire.
They are instructed to shout warnings at protesters approaching the
border, then, should those instructions be ignored, to fire warning
shots in the air, a military source said on Wednesday.

If marchers continue to approach the fence, troops are ordered to direct nonlethal fire at their lower bodies, the source said.

“We could also use tear gas and stun grenades. But we won’t tolerate the
idea that our international borders will become like Bil’in,” the
source said.
